Applied Physics Seminar: "Local Strain Engineering – A New Degree of Freedom for Optoelectronic Design"

Abstract: Controlling strain is an important consideration for the design of modern electronic and optoelectronic devices. Excessive strain leads to material defects and lowers device performance. An adequate amount of strain, on the other hand, can profoundly modify optoelectronic properties, resulting in new device capabilities. In this talk, I will review local strain engineering in gallium nitride semiconductors and how this leads to new functionalities that are otherwise difficult to attain. Demonstrations of potential applications in microdisplays, quantum information processing, robotics, and spectroscopic sensing will be discussed.
